Featuring super smooth CeramicSpeed grade 3 Silicon Nitride balls, each bearing is crafted with micron-level accuracy to perfectly match hardened steel raceways that boast an ultra-smooth polished groove. This meticulous engineering ensures minimal friction, enhancing your cycling efficiency and prolonging bearing life.\u003c\/p\u003e\n\n\u003cp\u003eThe reinforced polyamide cage securely holds the balls in place, while the low viscosity CeramicSpeed “Blue Grease” optimizes bearing performance by reducing friction and extending longevity. Non-contact seals protect the internals from dirt and moisture, making these bearings reliable across various cycling disciplines including Road, TT, Triathlon, Track, Cross, and MTB. With their superior hardness, smoothness, and load capacity, CeramicSpeed bearings significantly improve power transfer and overall ride quality.\u003c\/p\u003e\n\n\u003cp\u003eEach bearing undergoes four thorough hand inspections during assembly to ensure flawless matching of components. The CeramicSpeed balls outperform standard steel bearings with 400% smoother operation, 128% increased hardness, and 58% reduced weight. Compared to other ceramic balls, these are 15% harder, endure 99% higher loads, and are 100% smoother, setting the benchmark for cycling components worldwide.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eInner Diameter: 7mm\u003c\/li\u003e\n  \u003cli\u003eOuter Diameter: 19mm\u003c\/li\u003e\n  \u003cli\u003eWidth: 6mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eReducing friction to enhance cycling efficiency and speed\u003c\/li\u003e\n  \u003cli\u003eExtending bearing life through advanced materials and lubrication\u003c\/li\u003e\n  \u003cli\u003eProviding reliable performance across multiple cycling disciplines\u003c\/li\u003e\n  \u003cli\u003eImproving power transfer for a smoother, more responsive ride\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat It’s NOT Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eHeavy industrial applications beyond cycling components\u003c\/li\u003e\n  \u003cli\u003eUse in environments with excessive contamination without additional protection\u003c\/li\u003e\n  \u003cli\u003eNon-standard bearing size requirements outside 7mm x 19mm x 6mm dimensions\u003c\/li\u003e\n  \u003cli\u003eSituations where high maintenance or frequent replacement is acceptable\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eAre these bearings compatible with all bike hubs?\u003c\/strong\u003e\u003cbr\u003eThey are designed to fit hubs with a 7mm inner diameter and 19mm outer diameter.
